Being a questor gives you an extra virtue at 0 (named after your Passion).  You have to buy it up with XP (or bonus points, if creating a Questor).  Whenever you exemplify your Passion, roll your Passion Virtue and add the number of successes to your "Questor Pool".  When you attempt to instill that Passion in others, you have to make a perfectly ordinary Charisma+Passion roll; for each success, you can spend a point from your Questor Pool to give the target a bonus die.

Such exhortation is usually an important enough event to qualify for Unsung Legend Points, though not usually more than once/session.
